Answer 1

396 in²

Explanation:

To answer this question we need to use pythagorean theorem (a² + b² = c²)

In our case, a would be 14 and b would be 17

• 14² + 17² = ?²
• 196 + 289 = 485
• 
  `√(485)` = 22.02

Now we have to multiply this by 18

• 22.02 x 18 = 396.36

Which rounded would be 396

Hope this helps, have a lovely day! :)
